well as serving to overcomeL the liability of' forgetfulness to lock thegate vatthe, re-

quired time whicli'frequently occursfowing to the present forms of gatesofthis class being 'usually locked by the use of-separate locking means,such as padlocks which are frequently misplaced or forgotten at the ntime when the gate should be locked.A n

" The invention consists broadly of means providinga'socket on onefofthe opposing end rails ofl the; collapsible members of 'a `i foldablegate, and thesocket has preferably a substantially'rectangular ent-ranceof Vless dimension than the socket so that the edge portions `of thesides of the:y socket provide overhanging flanges. On the second-endrall is locking meanswhi'ch 4is operative only by a vkey lof 'a givenform, and the locking means includes an approximately T-shaped Abolt forallowing its cross-arms toenter, the entrance lengthwise of said socketwhen the end rails are closed ftogether by theikeyk be- Y ing partlyturned to unlock theflocking means yand to allow the cross-arms of thebolt kto engage the overhanging sidev flanges Vof thesoclret when theboltiis subsequently partly rrotated byl turning' the key to a positionforlocking the locking means. ,The members of the gate being extensibly.ad-v

justable ytoward and from each other may thereby be effectually lockedwhen closed against being surreptiti'ou'sly opened.v i

A further object of the invention is'gto provide a foldablegate ofasimple, eiicient yand Vdurable construction -Which may be made inappropriate sizes and shapes. .i With these and otherobjects inv View,the invention willv be hereina'jffter more l fully explained withreference Ato the accompanying drawing forming a part of thisv speci-lfication in which similar 'characters offref? erence indicatecorresponding parts in all the'views, and will then be pointed out inthe claims at'th-e end of the description.

The foldable gate has twoV collapsible members' y10 11 which maybe ofany of the commonly used extensibly adjustable forms, though the membersofthe gate illustrated are of the well known Bostwick type havingstructural parts whichneed not'V be lherein describedv since theirconstruction is gener# ally understood.V The "opposite ends of themembers 10, 11 of the gate yare suitably. supported in fixed positions-forallowing the spaced parallel verticalmails 12 ofk eachk membertobeslidably moved onthe lower and upper longitudinally disposed tracks orrails 13, 14 toward and from each other in ythe usual fashion when thegate is opened Y lengths, and the bars of each end rail are cacho-faU-shape in'crossl-section as well as .beingspaced apart 'at similardistances sothat the spaces between the bars of both rails' are inalinement.V The Ushaped bars of each end rail are disposed :with thefree edges of their legs inopposed relation and eachpair of the bars aresecuredk together byv spaced cross-bars vor bolts v19. Y Between' thelower ends of the bars 17, 18 of the end rail 15 is secured at 20 oneend of a short bar or block, as 21, and between the upper ends of thebars 17, 18 of this end rail is secured at 22 one end of a second shortbar or block 23. Both of the short bars 21, 23 protrude angularly fromthe end rail 15 for heilig received between the bats 17, 18 of the endrail 16 to guide the bars of the end rail 16 into contact with the barsof the end rail 15 when the collapsible members 10, 11 of the gate areclosed.

In the central part of the end rail 15 between its bars 17, 18 is asocket 24 of substantiallY a rectangular shape having a bottom wal 25,side walls 26, 27 and a front wall 28. In the central part of the frontwall 28 is an approximately rectangular' o ning or entrance 29 of a lessdimension t 1an the socket so that the edge portions of the entranceprovide ovcrhanging flanges 29, 29", 29, 29d. This socket may be formedby flattening a tube to a size so that the side walls 26, 27 snugly titin the pair oit U- shaped bars 17, 18 of the end rail 15, and thesidewalls of the socket may be secured, as at 30, 31 to the U-shaped bars otthe end rail. The sockethas a lower end wall 32 and an upper end wall33. Both of the end walls 32, 33 are preferably in the forms of barswhich may be welded or otherwise secured between the U-shaped bars ofthis end rail.

Between the central parts of the bars 17 18 of the end rail 16 is meansproviding a lock 31 having a casing 35 which is pref erablv of a formcomposed of a block or bar 36 of a length Somewhat longer than thesocket The block 36 is arranged between the pair of bars of the end rail16, and the end portions of this block are bolted, as at 37, 37, to thebars. Through the central art of the block 36 is an opening 38 which isadapted to be alined with the center of f the entrance 29 of the socket24 when the end rails 15, 16 are in contact with the closing of themembers 10, 11 of the gate, and the other end of the opening 38 may leadinto a recess 39 provided in the central part of the outer face of theblock. On the recessed face of the block 36 is another block or shortbar 40 havingr its end portions fastened. as at 41, 41, to the block 36.In the central part of the block 40 is an opening 42 which is largerthan the recess 39 of the block 36, and the lower part of the opening 42leads into the recess. In the opening 42 of the block 40 is suitably xedthe cylinder 43 of a lock 44 which may be of any well known combinationtype having the spring actuated spaced tumblers 45 adapted to be movedinto and out of the spaced orifices 46 of the barrel 17 having adetermined form of socket 48 for receiving the stem of a key, as 49, ofa given type as may be required to an angular hole. Protruding from thebarrel 47 is an angular stem or pin 52 which extends `through the hole51 of the cap plate 50 and through the recess 39 into the opening 38 of.the block 36. The projecting portion of the stem 52 is seated intherecess 53 in the free end of the leg or arm54 of a substantiallyT-shaped lock bolt 55. The crossarm `56` of the lock bolt is shorterthan the length of the entrance 29 of the `-ocket-24 of the end rail 15,but this cross-arm is `of a length so that .its protruding ends areadapted to engage the overhanging side flanges 29, 29b of the wall ofthe entrance of the socket. The lock bolt is also of such a length thatwhen inserted in the socket 24 its cross-` arm 56 may be rotativelymoved to `and from` crosswise and lengthwise positions in the socket.

In order to lock the gate the members 10, i

11 are moved toward each other so that the end rails 15, 16 are inproximity and so that the guide bars l21, 23 of the endl-ail 15 `aremoved between the pair others 17 18 of the end rail 16. must be in aposition so that the head or` arm 56 of the lock bolt `55 extendscrosswise of the end rail 16 before the key can be inserted in thebarrel of the lock.` Whenthe key is :inserted inthe barrel for operatingthe tumblers 45 the barrel and lock bolt are then turned half of `arevolution to dispose the cross-arm 56 of the lock bolt in a verticalposition. The members 10. 11 are then moved to cause contact of the endrails 15, 16 at which time the lock holt with its crossarm will passinto the socket 24 through its entrance 29, and by rotating the key one-The barrel 47 of the lock 34 i half of a revolution the barrel and boltof the lock will be likewise revolved `for positioning the cross-arm ofthe bolt crosswise of the interior of the socket into engagement withthe edge portions of the sides of the wall of the entrance. as shown indotted lines in Figs. 2 and .4 of the drawing. Thus the end rails 15. 16of the members of the gate must be locked together before the key can bewithdrawn from the lock. and b v requiring the use of the ke)Y in thismanner the liability offorgetfnlness to `lock the` any of the advantagesofthis invention,
